The needle on my temperature guage never reaches the middle temperature (210 F) It always fluctuates around the first quarter mark (100-150 F). I have already changed my thermostat and it made no difference. So what I am wondering is if this is normal for these trucks or is it causing damage. The heater provides good heat and the 4.3 L Vortec always runs smooth at this temperature.
